Hi,

I am a beginner looking for possible 8051 controllers which can be directly programmed using the RS232 serial PC port. I found a circuit which included an 89C51 which needed some additional firmware to be written on to it. I don't have a EPROM programmer so thats a no-go. Would highly appreciate suggestions.

Thanks

89C51 cant be programmed directly using serial port, to the best of my knowledge you should have a programmer.

89V51RD2 is the IC by NXP which supports programming through serial port without any programmer. You need to create a hex file through your compiler and then transfer it to MCU through FlashMagic tool.

For learning purpose, FlashMagic is freely available and its easy to use.

Let me know, if you want more help on this.
